TO ALL WHOM IT MAY CONCERN:

Be it known that I, 'ANSON A. AVERY, of. Cardiff, in the county of Onondaga, and State of New York, have invented a new and useful Improvement in churmDashers; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, formingpart of this specification, i-u'which Figure 1 is a top view of my improved churn-dasher.

Figure2 is a bottom viewof my improved churn-dnsher.

Figure 3 is a cross-section taken in the-line a: w, fig. 1.

Figure 4 is a 'cross-section taken in the line y y, fig.- 2.

Similar letters of reference indicate like parts. i

This invention reletes to an improvement in churn-dashors, and'consists in formingn dasher with a series of bars, fluted and slotted in such mannertthat the air is caught under and forced through them with the cream, so asto thoroughly intermingle in their passage through the bars, and thus produce the effect of an atmospheric churn upon the cream, bringing the butter quickly The handle A on one end is fastened to a cross-head, B, and oil-each end of this cross-head are fastened cross-beams, DJ), the'whole forming astrong square framework, 'On the under side of the dasher a-series of broad fingers, a a, is fastened on both sides of the cross-head B, extending as far it's the ends of" the crossbeams D D. These fingers are fluted or co ncuve on'the lowenside, as shown in fig. 4, the two outside fingers having their fluted surfaces in line with'the curve of similar concave surfaces in the under side of the crossbeamsl) D, so as to form together regular arches. The -middle finger is hollowed out like an inverted trough. In all the fingers a a are slots, 6 c, fig. 2. On the upper side of thedasher movable cross-burs, G C, are let into recesses in the ends of the cross-beams D D, to ivhich they are secured by buttons, at d, A series of fingers, e e, is attached to the cross-bars G C, pointing inward, and breaking joints over the l0\ver fingers a a. They are alsov hollowed out on the lower side like the lower fingers. The upper set of fingers is made movable for the purpose of cleaning'easily and thoroughly, and in the spring of the year, when.,butter is quickly made, they may be dispensed with, but in cool weather they promote the churning materially.

The dasher may be' advantageously operated with a lever connected with the upper end if desired.

Having described my invention, I claim as new, and desireto secure by Letters Patent The slotted and fluted fingers a a and e e, in combination with the cross-head B, and thebross-beams D D, arranged and operating substantially as herein describethv v ANSON A. AVERY.
